Collapsible door and window decorative article structure

ABSTRACT

A collapsible door and window decorative article structure comprises a set of counterweight boards attached to the bottoms of both lateral sides of a fan-shaped blind body. The underside of each counterweight board has a recessed groove with insert pieces symmetrically extending at both side edges. A support seat is mounted to a central hollow-out portion of the fan-shaped blind body, and a frame body of a door/window has a positioning seat with support legs and flexible guide hooks to fix to both sides of the top surface thereon respectively so that the counterweight board can be forced downward along the guide hooks, permitting the guide hooks to precisely engage with the insert pieces for location. In dismantling, the counterweight board is simply lifted upwards to detach from the positioning seat for replacement of the fan-shaped blind body, facilitating flexible and convenient dismantling and assembling of the present invention thereby.

BACKGROUND OF THE INVENTION

The present invention relates to a collapsible door and window decorative article structure, comprising a set of counterweight boards attached to both lateral sides of a fan-shaped blind body wherein support legs with flexible guide hooks of a positioning seat are utilized to reciprocally engage with insert pieces of each counterweight board so that the counterweight board can be easily assembled onto or detached from the positioning seat, facilitating flexible and convenient assembling/dismantling thereof as well as preventing any damages done to the fan-shaped blind body or glue remains left on a frame body of a door/window in the dismantling process thereof.

A conventional door/window 10 (referring to FIG. 1) is equipped with a frame body 101 decorated with a fan-shaped blind body 11. A support seat 12 composed of stop plates 121 and an arcuate support portion 122 is fixed to the top middle section of the frame body 101 thereon so as to hold in place a central hollow-out portion 111 of the fan-shaped blind body 11 thereby. Then, both lateral sides of the fan-shaped blind body 11 can be directly applied with double-sided fastening tapes or adhesive agent to adhere onto the top surface of the frame body 101 thereon as shown in FIG. 2.

There are some drawbacks to the afore-mentioned fan-shaped blind body structure. First, the fan-shaped blind body 11 is directly fastened to the top surface of the frame body 101. To replace the fan-shaped blind body 11, the fan-shaped blind body 11 fixedly fastened to the top surface of the frame body 11 must be removed there-from by force and, as a result, will be torn out of use. Thus, the conventional fan-shaped blind body 11 cannot be flexibly assembled or dismantled. Besides, after the fan-shaped blind body 11 is dismantled, the remains of the fastening agent tend to be left on the top surface of the frame body 101, which can also cause difficulty and trouble in cleaning thereof. Second, the fan-shaped blind body 11 is collected in plaited form. In assembly, after one bottom side of the fan-shaped blind body 11 is fastened onto the top surface of the frame body 101, the other bottom side of the fan-shaped blind body 11 must be held by hands to prevent the fan-shaped blind body 11 from folding backwards in the fastening process thereof, which can cause inconvenience in the assembly thereof.

SUMMARY OF THE PRESENT INVENTION

It is, therefore, the primary purpose of the present invention to provide a collapsible door and window decorative article structure, comprising a set of counterweight boards attached to both lateral sides of a fan-shaped blind body wherein support legs with flexible guide hooks of a positioning seat are utilized to reciprocally engage with insert pieces of each counterweight board so that the counterweight board can be easily detached from the positioning seat for replacement of the fan-shaped blind body to avoid any damages done to the fan-shaped blind body and the remains of fastening agent left on a door/window frame body, facilitating flexible and convenient dismantling/assembling as well as keeping the wholeness of the fan-shaped blind body thereby.

It is, therefore, the second purpose of the present invention to provide a collapsible door and window decorative article structure wherein, when the fan-shaped blind body is unfolded at both lateral sides, the weight of the counterweight boards can expand and locate the blind body naturally into a fan-like form without the bottom sides of the fan-shaped blind body being held by hands for the assembling process as found in the aforementioned prior art, achieving the best state of application thereby.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 3 showing an exploded perspective view of the present invention (accompanied by FIG. 4). The present invention relates to a collapsible door and window decorative article structure, comprising a fan-shaped blind body 20, and a set of counterweight boards 21 attached to the bottoms of both lateral sides of the fan-shaped blind body 20 so that the fan-shaped blind body 20 affected by the weight of the counterweight boards 21 can be naturally expanded at both lateral sides and positioned into a fan-like form thereby. The underside of the counterweight board 21 has an inverted U-shaped recessed groove 211 defining thereon, and perpendicular to both side edges of the recessed groove 211 are disposed a set of flexible insert pieces 212 symmetrically extending inwards thereon. And a support seat 30 composed of an arcuate support portion 31 and a set of stop plates 32 are mounted to a central hollow-out portion 201 of the fan-shaped blind body 20 thereof so that the fan-shaped blind body 20 can be precisely held in place by the arcuate support portion 31 and restricted in position by the two stop plates 32 disposed at both sides thereof. In addition, both lateral sides of the arcuate support portion 31 have a wing panel 33 with insert hooks 331 protruding thereon respectively to be accommodated into the recessed groove 211 of the counterweight board 21 and hooked to the insert pieces 212 for location thereby. Then, via double-sided fastening tapes or adhesive agent thereof, the bottom surface of the arcuate support portion 31 is then adhered onto the topside of a frame body 41 of a door/window 40. Furthermore, the frame body 41 can also have one or more than one positioning seat 50 (referring to FIG. 5) fixed to both sides of the top surface thereon respectively. The bottom surface of the positioning seat 50 can have double-sided fastening tapes or adhesive agent applied thereto so as to adhere onto the top surface of the frame body 41 thereby. The positioning seat 50 is equipped with a set of support legs 51 symmetrically protruding at on side surface thereon, and the end portion of each support leg 51 has a flexible guide hook 52 bent downwards to form an oblique conic configuration. Thus, when the counterweight board 21 of the fan-shaped blind body 20 is pressed downward along the guide hooks 52 as shown in FIG. 6, the flexible guide hooks 52 are precisely forced to accommodate into the recessed groove 211 and hook to the insert pieces 212 for secure location as shown in FIG. 7. Furthermore, both longitudinal side edges of the positioning seat 50 have a set of triangular support ribs 53 extending thereon to correspond to the guide hooks 52 so as to synchronically clamp the insert pieces 212 in position thereby. Finally, the end edge of each guide hook 52 is defined by an arcuate-shaped smooth surface 521 thereon, and the outer end edges of both counterweight boards 21 have an enclosure sheath 22 mounted thereto respectively.

To replace the fan-shaped blind body 20, the design of the positioning seat 50 is utilized wherein the support legs 51 with the flexible guide hooks 52 are reciprocally engaged with the insert pieces 212 of the counterweight board 21. In operation, the counterweight board 21 is simply pushed to one side and, then, bent upwards as shown in FIGS. 8, 9. Then, the insert piece 212 will be slid upwards along the smooth surface 521 of the guide hook 52 and the insert hook 331 of the wing panel 33 to detach from the positioning seat 50 so that the fan-shaped blind body 20 can be easily retrieved for replacement thereof. Therefore, the fan-shaped blind body 20 can be flexibly and conveniently dismantled as well as assembled. Besides, the fan-shaped blind body 20 can be protected from damages in the process of dismantling, and the door/window frame can also avoid remains of the adhesive agent left thereon as found in the afore-mentioned conventional fan-shaped blind body structure, achieving the best state of application of the present invention thereby.

Please refer to FIGS. 10, 11. The positioning seat 50 can also have multiple bores 54 drilled in the middle section thereon for the mounting of screws A to secure the positioning seat 50 onto the top surface of the frame body 41 thereby.

Please refer to FIG. 12. Each guide hook 52 of the positioning seat 50 can also have an oblique sloped surface 521′ or a flat abutment surface 521″ extending at the bottom edge thereon to fit to the insert piece 212 and reciprocally engage therewith for positioning thereby.

Please refer to FIG. 14. The present invention can also include one or more than one positioning seat 60 wherein the positioning seat 60 has a set of transverse V-shaped guide hooks 61 symmetrically protruding at the top surface thereon, and each guide hook 61 has a guide smooth surface 611 defining the upper and lower sections thereon respectively, permitting a flexible space 62 to form between both guide hooks 61. Thus, in assembly, the insert pieces 211 of the counterweight board 21 are allowed to slide along the guide smooth surfaces 611 disposed at the upper sections of the guide hooks 61 and pushed downwards to hook onto the guide smooth surfaces 611 disposed at the lower sections thereof. Otherwise, in dismantling thereof, the insert pieces 211 of the counterweight board 21 are glided along the lower guide smooth surfaces 611 and then lifted upwards to detach there-from.
